BEM ANALYSIS OF POTENTIAL DISTRIBUTION IN HARBOUR STRUCTURES UNDER CATHODIC PROTECTION

In this paper, a numerical analysis approach with the aid of boundary element method applicable to the cathodic protection problem of offshore structures, such as harbour piles and oil jackets, is developed, In the calculation model, the uniform electrolyte domain consisting of sea water and sea bottom mud is simplified to two uniform subregions divided by the water-mud interface. Based on this simplification, discretization of the interface between two subregions in the BEM analysis is avoided by using an adequate Green's function. After confirming the efficiency of the proposed method, an optimal design of the cathodic protection system for a harbour structure is performed.
